Will I need a stress test to diagnose atrial fibrillation?

Certain heart problems, like atrial fibrillation, may be easier to diagnose if your heart is working hard and beating fast. With an EKG (ECG) stress test, your doctor will observe your heart either while you are exercising or, if you are unable to exercise, while you are taking a medication to speed up your heart rate so your heart works hard and beats fast during the EKG. The EKG stress test may show your doctor the following:

- Any abnormal changes in your blood pressure and/or heart rate - Symptoms you may have reported such as chest pain under stress or during exercise - Any unusual changes in your heart's rhythm or electrical system - Problems such as valvular heart disease or heart failure

Your circulatory system is made up of your heart, blood, blood vessels and lungs. In your circulatory system your heart pumps blood transporting nutrients, water and oxygen to your bodys cells. Your circulatory system allows your lungs to rid the body of waste and carbon dioxide and bring oxygen into your blood.
Exercise and healthy eating are two ways you can help keep your circulatory system healthy. Smoking does damage to healthy blood circulation. When you smoke the carbon monoxide and nicotine entering your body have negative effects on your blood and blood vessels and constrict circulation.
Signs of poor circulation include cold hands and feet, numbness, dizziness, migraines, varicose veins and pain in your feet or legs. Consult a doctor if you have these symptoms. Untreated, poor circulation can lead to stroke, high blood pressure, kidney damage and other diseases.
